What is Answer Engine?
Answer Engines represent a paradigm shift from traditional search engines. While search engines like Google have historically returned ranked lists of links, answer engines use AI to synthesise a direct response to the user's question. The user receives an answer, not a menu of options to investigate.
The term "answer engine" encompasses a broad category of AI systems: standalone chatbots (ChatGPT, Claude), AI-native search engines (Perplexity), search engine AI features (AI Overviews, AI Mode), and integrated assistants (Microsoft Copilot). Despite their different interfaces and underlying technologies, all answer engines share the common characteristic of generating synthesised responses rather than link lists.
For brands, the shift from search engines to answer engines has profound implications. In the search engine model, being on page 1 of results was sufficient—users would click through and evaluate your site. In the answer engine model, the AI makes the evaluation for the user. If the answer engine doesn't mention your brand, the user may never know you exist.
This shift is driving the emergence of AEO as a discipline. Brands need to understand how each answer engine works, what content it prioritises, and how to optimise their digital presence to be included in AI-generated responses.
Why it matters
Answer engines are rapidly becoming the primary way consumers research products and services. Understanding the answer engine landscape is essential for any brand that depends on digital discovery. The shift from "10 blue links" to synthesised answers fundamentally changes how brands need to think about online visibility.

AEO (AI Engine Optimisation)
strategyIn marketing, AEO means AI Engine Optimisation: the practice of improving how a brand appears in AI-generated responses. It is not the customs and trade meaning of AEO. Instead, it focuses on visibility across ChatGPT, Perplexity, Gemini, Claude, and other answer engines.
AI Visibility
strategyAI Visibility refers to the extent to which a brand is present, accurately represented, and favourably positioned across AI engine responses. It is the aggregate measure of how discoverable your brand is when users ask AI engines questions relevant to your products or services.
Share of Model
metricShare of Model (SoM) measures how frequently a brand is mentioned or recommended by AI engines in response to relevant queries. It is the AI-era equivalent of Share of Voice, quantifying your brand's presence across ChatGPT, Perplexity, Gemini, Claude, and other answer engines.
